Furthermore, a plurality of pull rods are arranged in the filling cavity, and the pull rods are perpendicular to the inner wall of the filling cavity.

Furthermore, the position of the pull rod corresponds to the position of the reinforcing plate.

Furthermore, the box mould, the cushion block, the reinforcing plate and the pull rod are all made of high-strength steel.

Furthermore, a one-way valve is arranged on the feeding pipe.

Furthermore, the cushion block is of a hollow structure, and a damping mechanism is arranged inside the cushion block.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses in, the mode preparation shaping that the supporting device adopted the inside grout of box mould through the inlet pipe to filling the cavity in pouring concrete, partial concrete is full of the clearance between box mould and the tunnel through the via hole for box mould and tunnel combine inseparabler, the filling process adopts the mode that the pressurization was filled, so that the clearance between cavity and box mould and the tunnel is filled with in filling, concrete refluence when avoiding solidifying, the event is equipped with the check valve on the inlet pipe.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution:

the utility model provides a colliery tunnelling supporting device, box mould 1 including the structure of falling the U-shaped, be equipped with the determining deviation between the outer wall of box mould 1 and the wall in tunnel, and evenly be equipped with a plurality of via holes 2 on the outer wall that box mould 1 corresponds the wall, via hole 2 is with 1 inboard packing chamber 3 and outside intercommunication of box mould, two bottoms of box mould 1 all are equipped with cushion 4, evenly be equipped with a plurality of reinforcing plates 5 of falling the U-shaped structure on the inner wall of box mould 1, and the reinforcing plate 5 that corresponds on being located reinforcing plate 5 in the outside and the adjacent box mould 1 is bolted fixedly, the inboard top surface of box mould 1 is equipped with inlet pipe 6, and inlet pipe 6 runs through box mould 1 and extends to the inboard upper portion of packing chamber 3.

In this scheme, the mode preparation shaping that supporting device adopted the inside grout of box mould 1, pour the concrete in 3 to filling the chamber through inlet pipe 6, partial concrete is full of the clearance between box mould 1 and the tunnel through via hole 2, make box mould 1 inseparabler with the tunnel combination, the mode that the process of pouring adopted the pressurization to pour into, so that the clearance between filling chamber 3 and box mould 1 and the tunnel is full of, concrete refluence when avoiding solidifying, the event is equipped with the check valve on inlet pipe 6.

Wherein, for making the concrete of filling 3 insides of chamber and the combination of chamber wall more firm, so locate a plurality of pull rods 7 in the inside of filling 3, and pull rod 7 is perpendicular with the inner wall of filling 3, and when the concrete solidification back, pull rod 7 rigidity can keep tank wall and concrete to closely laminate all the time.

In addition, the position of the pull rod 7 corresponds to the position of the reinforcing plate 5, so that when the pull rod 7 is extruded on two sides of a roadway, the extrusion acting force is more favorably transmitted to the reinforcing plate 5.

The box mould 1, the cushion block 4, the reinforcing plate 5 and the pull rod 7 are all made of high-strength steel, the structural strength of the formed body is improved, the outer wall of the box mould 1 is matched with concrete to form the effect of reinforced concrete, and the structural strength is better.
